and Angelina Jolie's relationship
has been transformed by couples' yoga.
The Hollywood stars - who raise six children together, Maddox, nine, Pax, seven, Zahara, five, Shiloh, four, and two-year-old twins Knox and Vivienne - have been working with Indian spiritual teacher Guru Ram Lalji to bring harmony to their five-year union.
A source told Now magazine: "They've been practising his Siddha yoga
and they start and end the day by chanting a sacred word he's given them.
"It's transformed their relationship - they've both cut back on drinking and no longer argue."
Brad and Angelina are not the only couple to practise yoga together.
It was recently revealed that David and Victoria Beckham
have developed an interest in the relaxation technique and attend regular sessions together.
A source said: "Victoria and David do power yoga classes for couples for an hour about twice a week.
"It's a very intimate experience. You have to learn to become one entity entirely. You stretch, breathe and move as one - it's great for couples and probably better than talking in a way.
"They started taking the classes about a year ago and it's astonishing how in tune with each other they are these days."
